Dark Matter
Most of us grew up hearing about how our universe is composed of normal matter. Matter was described as being composed of a nucleuses composed of particles called neutrons and protons, composed of sub atomic particles called quarks, and being orbited by positively charged particles called electrons,,
We were taught that gravity, the force that keeps celestial objects in their orbits, is produced or caused by matter, and that the velocity of celestial objects in orbit, was determined by the quantity of matter that they interacted with. The stronger the gravity in relation to the object, the faster the object in orbit would need to travel in order to prevent itself from being pulled in.
This concept predominated as a firmly-established, irrefutable fact, until just recently when the motions of the stars in orbit within our galaxy, and then others, were discovered to be completely out of kilter with the detectable matter that they were interacting with. Instead of decreasing in velocity in saccordance with their distances from the galactic centers, they were maintaining their velocities. Of course, the only explanation was that they were reacting to matter that was not being detected.
So since no detectable matter was ever discovered to be responsible, scientists decided to call whatever is causing this discrepancy, as Dark Matter. Which of course is just a face-saving-fancy way of simply admitting that they don't know. In this video, the history of dark matter and speculations as to what exactly it might chance to be is considered in detail.
